Then one gets some errors during a reboot as Monit cannot connect to the mailserver at this time, which is normal since the mail server has been stopped before Monit. This is not a problem, as I will receive the mail after the reboot. The problem is the "Queued event file: unable to read event size -- end of file" errors every 2 minutes after the reboot, which fill my log file. This may be a long-standing bug, which I hadn't noticed until now. In my monitrc file, I have in particular: set mailserver localhost set alert [email protected] -- Package-specific info: Monit config file /etc/monit/monitrc is *NOT* readable by reportbug. Please, consider to rerun reportbug as root and *carefully* examine reportbug's output (e.g., monitrc content), before sending it out.
